MAKING HEADS oF cAsKsl Specification forming part of Letters Patent No. 46,71 dated March 7, 1865.

Be- -it known that I, E. B. SPAULD1NG,of St. Louis, in the county of St. Louis and State ot Missouri, havev invented new and usetul Improvements in Machines forCutting Heads, 0f Kegs, Sto.; and I do hereby declare that the following is a full, clear, and exact de scription thereof, which will .enable those skilled in the art to make and use the same, reference .being had to the accompanying drawings, forming part of this specification, in which- I Figure l represents an elevation of my machine as seen from the front. Fig. 2is a plan sponding parts.

A is the frame of a lathe, supporting stand? ards A', which furnish suitable bea-rings for the mandrel C and arbor or shaft b. The shaft b has upon it a fast and aloose pulley, a e, constructed and operated iu the usual manner.

D is a socket, which supports within it a Similar letters of refe ence indicate corremandrel, C', which is operated by a screw and hand-wheel in a manner common inlathes. The arbor or shaft bis fixed in its bearings, so that it has'no longitudinal movement, but

of rotary motion, while the mandrel O. is capable only-ot" longitudinal motion'. Each has a disk, I,' on itsinner end, whose fiat faces are opposite to'each other, and one of which should havedogs on its surface to take into the stuft' and cause it to rotate with the disks, which'are suitably secured to the arbor and mandrel by means of collars, that 'on the arbor b being tixed so as to turn with it,

and that 611 the mandrel being so attached as to .be capable of rotation thereon.. When the mandrel is moved inward by its screw-wheel H,its disk I approaches the diskl of the arf Vbor, andvby that means any interposed sub;

stance or article is held rigidly between them the shaft.n On the 'ont of the` frame A, about midway. ofJ its'length,

' is fixed a platform, Q, which extends outward,

It has ways formed asf-seen in the'gures. l

and guidethe slid-f uponits surface'to retain ,in g table'R which is made to move in and out upon `the platform-Q by means of a screw, which revolves in a bearing on the under side of the table l?, and works through a screw,- tg: 'springing 'up from the plat tapped collar,

stocks B and: Gat top,set at Aare necessary for the work form Q.- A standard, g, rises vertically from the front of the table P, Behind it are two low standards, 3,- xed-'near the opposite sides of the' table P inA such positions as to furnish-bearings for thel fulcrums y of tool-bearing arms GL'which vibrate thereon in obedience' to themovements of the hand-lever E. The arms G rise vertically above their fulcrums, and are connected t0 each other by two links, k, one of which is fixed loosely to each of, the arms, and their vloose or inner ends fixed to the face of a short connecting-bar, 2, near the ends thereof, which bar is firmly secured upon ,the inner end of' the fulcrum-pin 3 of the lever E. This ful- Crum-pin is journaled in the standard g and in a bracket, d, secured to the foot vof thev standard: The arms G a'reinade of the shape seen in the drawings, projecting at their upper ends toward the disk l, and formed with toolsuch angles as A to be done, carrying cutters or planes B2 C t The inner faces ofthe arms at top are inclined atan obtuse angle with the lower 'part of the arms, as clearly seen in Fig. 2, in'order that the planes in the plane-stocks B shall give the right bevel to the edge of the stuit' wrought upon by.

them. The stocks B receive planes, which a1 ev fitted in the usual manner. The stocks Oreceive cutters such as are common in turning: lathes. They are set above the planes, and are composed of plates which clamp the cut -ters in grooves made in the arms by means of setscrews. The left-hand arm, G, is provided Awith a boss, h, (seen inl Fig. 1,) on its innerside,

against which.l an adjusting-screw, o, works. vThe arms move to and-from each other'in the same pla-ne, being, operated by the lever E and by` the adj usting-screw o. The platform Q can be adjusted upon the frameA so as to present the arms and their tools in a proper position opposite the stuff between the heads or disks I. f

-The operation is as follows: A square piece of stuff is put in the ylathe between the disks and secured firmly. It i'sthen rapidly rotated. l'lheleverE is then depressed "so as to gradually rotate the bar 2, andthereby, 4by means bring the arms andtheir cuttersof the links, l y v andplanes toward each other-,when the cutters will come' in contact with the stuff and U, one of which Yis seen in Fig".

cnt a circular groove on eachside of it, the parts cut away flying' oliC by centrifugal force. Next the planes commence to act and reduce the stuff to the desiredv bevel on each of its sides. The adjusting-screw o determines the thickness to which the stn" is to be brought on its edge; s

My machine is capable of operating upon any stuff which can be held by the disks, and

itis intended more especiallyA for cutting out y bottoms for pails and tubs and the bottoms and heads of kegs and finishing them at one operation.

' It will be seen that the cutters are set so` as to Work at right angles against th'e stuff', While the 'chamering-planes are at such an angle as to produce the proper bevel. The arms Gr are advanced toward the Work by means ofthe hand-Wheel B and screw S, and I .ain-thereby enabled to cutout Work for any4 sized pail, keg, or other article-2 I claim as new and desire to secure by hLetters Patent,- l.v The combination, in a lathe, ofthe rotating disks or heads I, the vibrating arms carrying; toolsfor cutting ont and chamferiag' the heads of kegs and other AWork of like character., and the sliding table which carries the arms, substantiaily as and for, the purpose described.

Constructing and arranging the chain- 'ering tool-stock B and the cutting toolstock C, in the order and manner herein shown, upon vibrating arms constructed and operated so as to be adjustable for different diameters and sizes of Wi rk and for different Jrhicknesses of' DANIEL W.
